You need to prove yourself.

"What's your name, girl?" Asked one of the soldiers, a tall man carrying an M60 heavy machine gun. Chains of bullets hung off his muscular frame, Rambo-style.

"Alex Smith", you stated in a trembling voice. The others were still training their weapons on you. "Relax, guys. Look, I'm unarmed and naked. I ain't gonna hurt you OK?"

"Sorry, Alex", said one of the women, a tall blonde whose flak jacket doesn't hide her ample bosoms and slim body. "Some of those caught by the plants can still stay under their control even when it's been destroyed. We need to make sure you're clean"

"For Christ's sake. Look, I'm clean OK. How can I prove it?" you plead. Nervous at this group with itchy trigger fingers.

"Well, one thing is that those who are infected can't seem to get turned on by humans. A kinda sick grief thing, I guess" said the leggy brunette. Unzipping her top, revealing her small, but well formed tits, she added, "Are you ready to prove yourself?"
